CTP 3 A, LED, AAA
<b>The cable tester CTP 3 A facilitates finding the right cable!</b>
Just plug the tester to one end of the cable (e.g. in the apartment) and hold the beeper to the other end (e.g. in the cellar). If there is a beep, you found the right cable.
The cable tester also shows short circuits with a red LED at the top of the device.
Shipment: cable tester with beeper, adaptor and micro- / AAA battery.
